According to the alert, the risk actors haven’t revealed their location to contacts within the ransomware affiliate and have been intentionally imprecise about their nationality and fatherland.
Officials mentioned that as of July, these attackers had been noticed “scanning IP addresses internet hosting Check Point Security Gateways for units probably weak to CVE2024-24919.”
Since April, risk actors have been conducting mass scans of IP addresses internet hosting Palo Alto Networks PAN-OS and GlobalProtect VPN units, “seemingly conducting reconnaissance actions,” probing for units weak to distant code execution.
The technical particulars add to and replace earlier advisories about Iran-based VPN vulnerability exploitation first printed by the FBI and CISA in 2020.
Officials encourage organizations to observe the instructed mitigation measures to guard themselves towards makes an attempt by Iranian cyber actors to achieve a foothold on their networks.
“These mitigation measures are per cross-sector cybersecurity efficiency targets established by CISA and the National Institute of Standards and Technology,” they famous.
Larger traits
Earlier this yr, the FBI, CISA and Department of Health and Human Services up to date their joint ALPHV Blackcat cybersecurity alert to handle new indicators of compromise concentrating on the healthcare sector.
“Of the roughly 70 victims uncovered since mid-December 2023, the healthcare sector has been essentially the most affected,” they mentioned.
The FBI claimed to have seized Russia-based ALPHV’s darknet web site and infrastructure late final yr, with the ransomware group allegedly claiming to have stolen 6TB of information from main insurance coverage claims processor Change Healthcare after it was taken offline following a large assault in February.
Be on report
“Initial intrusions by Iranian cyber actors depend on the exploitation of distant exterior providers on internet-facing property to achieve preliminary entry to sufferer networks,” FBI and CISA officers mentioned within the advisory.
